Exercise 2 Page 341

We want to simplify the given exponential expression. y^9/y^7 Notice that this expression is the quotient of two powers with the same base. Therefore, we can use the Quotient of Powers Property. This property states that when dividing two exponential expressions with the same base, we subtract the exponents.
y^9/y^7
y^(9 - 7)
y^2
